Abstract/ Executive Summary:

Twelve promising brinjal lines/varieties viz. SM011, SM019, SM020, SM121, SM182, SM183, SM191, BL072, Tarapuri, BARI Begun-4, BARI Begun-7, BARI Begun-8 were against brinjal shoot and fruit borer, jassid and red mite at Horticulture Research Centre, BARI, Gazipur during 2009-10 in a 12X12 Latin Square Design. Among the tested lines/varieties, three lines (SM020, BARI begun-7 and SM19-83) found highly resistant to brinjal shoot and fruit borer. On the other hand, lines BL072, SM011 and SM191 and variety Tarapuri received lower infestation ranged from 6.25-9.09% which classified as tolerant. Rest of the lines/varieties BARI begun-4, BARI begun-8, SM019 and SM021 received infestation ranged from 16.13-36.36% which were classified as susceptible. Lines SM020, SM011 and SM191 and variety Tarapuri were found tolerant to jassid. Only one line SM011 was found susceptible to red mite. Results also indicated that lines SM020, SM011 and SM191 and variety Tarapuri showed multiple tolerance against binjal shoot and fruit borer, jassid and red mite in the present study.

Keywords: Brinjal, Resistant, Brinjal shoot and fruit borer.

Location: Horticulture Research Centre, BARI, Gazipur

Start Date: 01-10-2009

End Date: 31-03-2010

Program Area: Pest Management

Commodity: Brinjal

Objectives:

To identify promising brinjal lines resistant to brinjal shoot and fruit borer.

Methodology:

A study was conducted at the central experimental farm of Horticulture Research Centre (HRC), BARI, Gazipur during 2009-10. Twelve promising brinjal lines/varieties viz. SM011, SM019, SM020, SM121, SM182, SM183, SM191, BL072, Tarapuri, BARI Begun-4, BARI Begun-7, BARI Begun-8 were tested in this study. Seedlings were transplanted in the main field in a 12X12 Latin Square design, where individual plot size was 10 x 1 m². Data on number of healthy and brinjal shoot and fruit borer damage fruits and number of hopper burned leaves infested by jassid from each plant, number of red mite infested plants and marketable fruit yield were recorded at 15 days interval.
